The close-knit sisters share everything—boyfriends, fuck buddies, even dicks and sperm! If the younger sister is having sex, she calls her older sister over; if the older sister is having sex, she calls her younger sister over, and they happily engage in a threesome. If either of them finds my erect dick, they share it together and make me cum inside each of them an equal number of times. In the end, even the sperm swallowed during oral sex is split evenly. Of course, sex has to be fair for both, so now I'm completely exhausted... But being able to enjoy such a perverted threesome is incredibly lucky!
